Oracle GridLink DataSource for SOA 11g
Oracle GridLink
DataSource:
Starting from version 10.3.4 Oracle
WebLogic introduces Oracle Gridlink DataSource which supports Oracle Database
11g R2 Grid based RAC.
During the SOA 11g installation
we donot have the option to enter the Grid based DataSource details.
So all the default DataSources are created as 'Generic'.
In case if you run into issues with
current DataSources. Please recreate DataSources as 'Gridlink
DataSources'.
Make sure all the default parameters
and values of 'Generic' Datasources are entered in 'GridLink' Datasources
as well.
Please use below documentation as
reference for creation of 'GridLink Datasources'

SOA Cluster High Availability for File Adapters - Findings
SOA 11g ps4: 11.1.1.5
File Adapter:
File and FTP Adapter have singleton functionality. In SOA 10g we should have deployed that File Adapter polling process on only one of the server in a cluster. In this way we have lost High availabiltiy functionality for the File Adpater process.
This problem has been solved in SOA 11g by adding the below configurations.
1. Login to Admin Console
2. SOADomain -> Deployments -> FileAdapter -> Configuration -> OutboundConnectionpools
3. Select 'eis/HAFileAdapter'
4. Change the controlDir property to some shared location Eg : /app/oracle/share/soadomain/soacluster/FileAdpater/controlDir
5. Save and Activate changes.
6. From Deployments , Select FileAdapter and update with new 'Plan.xml' . Make sure that 'Plan.xml' is located in shared location. E.g.: /app/oracle/share/soadomain/soacluster/FileAdapter/dp/Plan.xml
7. Save and Activate the changes.
8. Update the Adapter configuration to use the connection factory as shown in the following example:
<connection-factory location="eis/HAFileAdapter" adapterRef=""/>

SOA Cluster High Availability for DB Adapters - Findings
SOA 11g version: 11.1.1.5
DB Adapter:
1. Create a Datasource
2. Create a Connection pool
Steps: SOADomain -> Deployments -> DbAdapter -> Configuration -> OutboundConnectionPools -> Create 'New" connection pool.
3. Save and Activate the changes. At this point if you observer 'DbAdapter' is in 'Prepeared' state. We have to update the 'Dbadapter' by selecting the changed 'Plan.xml'.
4. When try to update and deploy the 'DbAdapter'. It will fail saying 'Location for 'Plan.xml' is not found.
Solution: Change the location of the Plan.xml from its original location in '$ORACLE_HOME/Oracle_SOA1/soa/connectors' to '$SHARED_LOCATION/Dbadapter/'
Updated the DbAdapter and target to soacluster and activate the changes.
Still the 'DbAdapter' is in 'prepared' state.
Restart the managed servers. Now you will see the 'DbAdapter' in Active State.
